BOOKMABKER.

Appication filed. April 16, 1923. Serial No. 632,396.

To all whom it may concern:

Be it known that I, JOHN WILLIAM HAR- RISON, a subject of the King of Great Britain and Ireland, residing at Preston, in the county of Lancaster, England, have invented certain new and useful Improvements in Bookmarkers, of which the following is a specification.

This invention relates to an improved book marker of the kind that is adapted to be de tachably secured to the covers of the book by clips and is automatically forced between and out of the leaves as .the book is closed and opened.

According to this invention the book marker comprises a short length 'of narrow material such as woven ribbon elastic folded at the centre and secured close to the fold. The ends of the material are cut in a slant ing direction, folded and secured, so that they are strengthened along one edge and such folded portions are then attached to suitable clips that are adapted to grip the book covers. With this construction when the book is being closed, the centre fold draws the material between the last open pages and when the book is opened, the ma terial turns over the obliquely cut edges which causes it to be moved clear of the pages whether the book is held in a vertical, inclined, horizontal, or an upside down position.

In the accompanying drawings Figure 1 is an inverted plan and Figure 2 an elevation of a book marker constructed in accordance with this invention.

Figure 3 shows the book marker applied to a book showing the position it assumes when the book is in its folded position, and

Figure 4 is a similar view showing the position assumed by the marker when the book is opened.

A indicates a length of elastic webbing or tape that is folded in the centre at a and sewn at a across the fold. The ends of the webbing or tape are folded and out in a slanting direction as shown at a in Figure l and such folded ends are sewn along the edges a and the slanting edges a Attached to each folded end by sewing is a metal or other clip B that is adapted to clip to the book back 0 as shown in Figures 3 and l.

In applying the book marker to a book back, the clips are attached to the latter in such manner that the strengthened edges face the hinged portion of the book so that as the book is opened the elastic webbing or tape is caused to turn along the obliquely cut edges and to be moved clear of the leaves as shown in Figure 4:. As the book is closed, the webbing or tape moves in the opposite direction and the centrally folded portion (1 draws the webbing between the last open pa es.

What I claim as my invention and desire to secure by Letters Patent in the United States is 1. A book marker, comprising a strip of elastic material folded double and adapted for insertion between the pages of a book, and clips secured to the. ends of the said strip and adapted to engage with the covers of the book and operating to move the strip clear of the pages when the book is opened.

2. A book marker as set forth in claim I, the end portions of the said strip being out diagonally and folded over to reinforce them and strengthen their connection with the said cli s.

l n testimony whereof I afiiX my signature.

JOHN WILLIAM HARRISON.
